To be the method that described equipment carbon nano-tube film depositing is used in the example explanation with the 3rd embodiment of the equipment of carbon nano-tube film depositing of the present invention below, and see also Fig. 8, it may further comprise the steps:
One base material 60 is provided.Base material 60 materials can be not and carbon reaction or material that can dissolved carbon, and need have high melt point, generally need be higher than 1000 ℃, and it can select silica, tin indium oxide or lead etc. for use.
On base material 60 surfaces, form a pattern intermediate layer 61 with definite shape.Described pattern intermediate layer 61 can be selected following material for use: the material of solubilized carbon, as iron, cobalt, nickel, manganese etc.; Can form the material of carbide, as silicon, molybdenum, titanium, tungsten, tantalum, niobium, zirconium, vanadium, chromium; Low-melting-point metal (700 ℃ or lower) is as aluminium, tin, palladium, zinc.Pattern intermediate layer 61 thickness are generally the 10-100 nanometer.It can adopt sputter, evaporation or chemical gaseous phase depositing process to prepare film, utilizes the pattern form of photoetching to obtain being scheduled to again.
Utilize equipment jet deposition one uniform carbon nano-tube solution film on base material of equipment the 3rd embodiment of carbon nano-tube film depositing of the present invention.Carbon nano-tube solution can be dissolved in methyl alcohol, ethanol and other lower alcohol solvent by CNT and make.During injection, make injection apparatus be arranged on appropriate location, base material 60 top.Base material 60 along continuous straight runs are moved, and arrow is represented base material 60 moving directions among the figure.Adjust bracing or strutting arrangement 31 and make its parallel surface at base material 60 and vertical with the moving direction of base material 60, like this then can be fast at the carbon nano-tube solution film of surface deposition one uniform film thickness of base material 60.CNT 62 is evenly distributed on the surface of base material 60, certainly, only is schematic diagram among the figure, and actual carbon nanotube density is far longer than shown in the figure.
Adjust the translational speed of base material 60, can change the thickness of the carbon nano-tube solution film that is ejected into base material 60 surfaces, base material 60 translational speeds are fast more, and then the carbon nano-tube solution film on base material 60 surfaces is thin more.Also can utilize adjusting device 34 to regulate the carbon nano-tube solution film thickness that the carbon nano-tube solution emitted dose is regulated base material 60 surfaces.
Certainly, it is static that base material 60 can keep, and bracing or strutting arrangement 31 is moved relative to base material 60.Perhaps base material 60 moves simultaneously with bracing or strutting arrangement 31.
Remove directly be deposited on base material 60 lip-deep CNTs 62 a base material 60 that only on pattern intermediate layer 61, is formed with carbon nano-tube film.Since between CNT 62 and the base material 60 adhesion a little less than, the removal process is easy to carry out.Adoptable method has flushing, ultrasonic degradation or blowing etc.Ultrasonic degradation generally need carry out 0.5 to 24 hour.
Utilize the prepared carbon nano-tube film thickness with pattern form of this method to be generally 10 nanometers to 1000 nanometers, it can be applicable to various fields such as flat-panel monitor, electron microscope etc.
